Polaris RZR XP 900 Lightweight Radius Rod Kit

Racer Tech's RZR XP 900 Lightweight Radius Rod Kit will replace the weak factory radius rods with a substantially stronger design. Here's the fix for the weakest link on the RZR XP 900. This is our lightweight, economical solution for the MX racers and recreational riders out there. These rods are substantially stronger than the OEM rods and also adjustable. These Radius Rods are a direct bolt-on replacement and work with the OEM trailing arm and knuckle/spindle. They are swedged 7075 aluminum rods with high strength 5/8" heim joints. The rods have a little room for adjustments for the inclined rider to tweak the handling a little bit if desired. The adjustment provided from this kit is the static camber settings. By adjusting the rear camber one can control how aggressive the bite of the rear tire is in a corner and find a preferred balance of understeer / oversteer which is how much the machine pushes or slides out in a corner. This setting while controlling handling going into a corner, can also fine tune traction coming out of a turn.

This kit complete with heim joints and hi misalignment spacers actually weighs 5 lbs. LESS than the weak OEM rods!

This kit includes BARE aluminum radius rods, heim joints and high misalignment spacers needed for installation. The factory bolts are re-used and there is no modification to the vehicle necessary.

This kit WILL work with our Radlock for paralleled rear suspension strength.

A lot of people have asked about our stance on bent lower rods for better ground clearance and why we haven't offered them. Here is where we stand on the subject; the issue with any bent / trussed/ etc. design (beside the inherent weakness added by having a rod that's already bent) is the additional leverage applied when something does try to wrap around the bar and tug on it. When it's a straight tube there is only a two dimensional push/pull on the rod. If it's a bend of any kind it's a three dimensional situation and the center to center axis of the ends becomes a fulcrum point for the bent tube to rotate about while it's being pulled or pushed. Essentially the rod will just try to flop around. The biggest issue with this particular application is the ends need to be a form of a spherical joint to work with the motion of the suspension. If this was some sort of a bushing/sleeve application the bent rod would be no problem. These new rods are going to be very hard to bend or break even if they do hit something.
